ROYAL BRENNAMAN, OF FRANCESVILLE, INDIANA.

WEATHER-STRIP.

SPECIFICATION forming part of Letters Patent No. 435,658, datedSeptember 2, 1890.

Application filed January 28, 1890. Serial No. 338,411. (No model.)

.To all whom it may concern:

Be it known that I, ROYAL BRENNAMAN, a citizen of the United States,residing at Francesville, in the county of Pulaski and State of Indiana,have invented a new and useful Weather-Strip, of which the following isa specification.

This invention relates to weather-strips more particularly of that classadapted for use at the bottom of an outside door; and the same consistsof astationary door-sill, a leaf hinged thereto, and springs for holdingsaid leaf with a yielding pressure upwardly above the sill, togetherwith certain details of construction and arrangements of parts, all ashereinafter more fully described, and illustrated in the accompanyin gdrawings, in which- Figure 1 is avertical section through a doorframeprovided with my improved sill, the door being shown as closed. Fig. 2is a similar view with the door open. Fig. 3 is a perspective view ofthe sill with the leaf lifted.

The letter F designates the door-frame, in which the door D is hinged inthe usual orin any preferred manner.

The letter S designates the sill of said doorframe havingashoulder snearits outer edge and provided with holes U, if desired, by means of whichitmay be screwed to the floor. The upper face of the sill S near itsinner edge is provided with a cylindrical groove G, which is open edonly for a small arc of acircle a, and in this groove closely fits thehead H of the leaf L, said head being connected with the leaf by anarrow neck 72, as shown. This leaf L is thereby pivoted within thegroove G, so that it may be lifted to the position shown in Fig. 3 whenit is desired to have access beneath the leaf for the purpose ofcleaning out dirt or ice that may accumulate therein. Along the frontedge of the leaf L is formed a depending flange or lip Z, which slidesagainst the front face of the shoulder s, as clearly shown in Fig. 2.Within the upper face of the sillS is formed one or more re cesses O,and seated in these recesses are coiled or bent leaf-springs G, whichexert a gentle upward pressure upon the leaf L, as will be clearlyunderstood.

The parts of this device being properly assembled, its operation is asfollows: When the door is closed, its lower edge passes freely over thepoint of connection between the head H and groove G; but as the doorpasses to its completely-closed position its lower edge strikes theupwardly-inclined leaf L and depresses the latter slightly against theforce of the springs G, which are beneath it. The leaf L will bedepressed and the springs G compressed to some degree, and the upperface of this leaf will always press tightly against the lower edge ofthe door when the latter is closed. As soon as the dooris opened theparts assume their normal position, in which they do not interfere withthe entrance or exit of persons over the sill. The sill S outside of theshoulders is preferably beveled off so that snow and ice willbedeflected from the door, and the lower edge of the lip Z is alsopreferably beveled, as shown at If, so that if ice and dirt shouldaccumulate and stand upon the beveled portion '1 and the door shouldafterward be closed the sharp lower edge of the lip will wedge itselfbehind such ice as it descends, and the operation of the leaf L will beunimpeded. Said leaf can be raised, as shown in Fig. 3, when it isdesired to clean the sill beneath the leaf or to replace or repair thesprings, and when it is desired to remove the leaf the sill S must befirst removed by withdrawing its fasteningscrews, and the leaf L thendrawn longitudinally from the sill S, so as to disengage its head H fromthe groove G.

Having described my invention, what I claim is 1. The sill S, bowedupwardly in its body and having the shoulders near its outer edge, incombination with the leaf L, hinged along the inner edge of the sillandprovided with a depending lip Z, sliding over said shoulder, andsprings pressing said leaf normally upward, substantially as described.

2. The sill S, provided with the vertical shoulder 5 near its outer edgeand beveled off, as at T, in front of said shoulder, in combination withthe leaf L, hinged along the inner edge of the sill and provided with adepending lip Z, sliding over said shoulder, said lip being beveled onits front face, as at t, to a point along its lower edge for the purposeset forth, and springs pressing said leaf normally upward, substantiallyas described.

3. The sill S, detachably secured along the bottom of the door-frame F,and the upwardly spring-pressed leaf L, pivoted to said sill along itsinner edge, in combination with the door D, swinging in a plane parallelto that 5 of the sill, the lower edge of the door depressing the leaf asthe former is closed, as and for the purpose set forth.

4. The sill S, detachably secured along the bottom of the door-frame F,in combination IO with the upwardly spring-pressed leaf L, pivoted tosaid sill along its inner edge, as and for the purpose set forth.

5. The sill S, provided with the longitudinal cylindrical groove G inits upper face, said groove being open at a through an arc of a circle,in combination with the leaf L, having
